BPG 8506
Properties
BPG 8506 is a high-performance sheet made of expanded graphite reinforced with a 0.05 mm flat stainless steel foil (316L). The reinforcement enhances handling properties, providing strength, stability, and reliable sealing performance in demanding industrial applications.
Applications
BPG 8506 delivers high compressibility and excellent resistance to creep, making it a reliable solution for challenging operating conditions. It is particularly suitable for petrochemical, chemical, process, and power plant industries, with proven performance in pumps, valves, compressors, and flange connections.
